The primary feature of a Content Management System (CMS) is its ability to simplify the creation, management, and modification of digital content. A CMS provides an intuitive interface that allows users, even those without programming skills, to publish content, manage files, and control user access. Popular CMS platforms like WordPress, Joomla, and Drupal offer templates and plugins to enhance functionality and design. This reduces the technical barriers to content creation, empowering organizations to maintain and update their websites effectively.
